Opening Robo Help and saved image is gone
When I insert and image into Robo Help and save and close the program, when I got back in the image is missing, but a large square is in its place. All the text is moved below the image, it seems to still be referencing it but I can't see it. When I originally insert it, it is in the correct place and sized correctly without me doing any adjustments to it. Then when I re-open robo help it is gone, any suggestions?
Please see the sticky thread Before You Post at http://forums.adobe.com/community/robohelp/robohelp_html
You haven't told us what version of RoboHelp you are using.
Also is your project saved locally or on a network drive?
See www.grainge.org for RoboHelp and Authoring tips

Can anyone give me suggestions .. after creating a "logo" or a "header" to be used by someone else in a presentation or report.. I can't figure out how to make the background transparent, and keep the image clear. Created in CS6 Illustrator.. tried opening in Photoshop and saving as JPEG.. no luck.
Have you tried exporting for MS Office?
You could also try exporting as transparent PNG with 144 ppi.
On top of that: don't scale it in Office. -
I had set up my new tab page with an image I uploaded. It worked fine for months, if not years.
Today, I got a 'crash' that asked me to start Firefox in 'safe' mode or 'restore'. I chose 'restore'.
Thereupon, my image was gone from my new tab page. I cannot find how to restore it, and add ons that supposedly allow me to add my own image are not helpful. At least, I cannot figure them out.
Can you provide help on a computer for dummies level?Sounds that you have reset Firefox and created a new profile.
You can try to create a new profile or reset Firefox.
*https://support.mozilla.org/kb/Managing+profiles
*https://support.mozilla.org/kb/reset-firefox-easily-fix-most-problems
When you reset Firefox then a new profile is created and some personal data (bookmarks, history, cookies, passwords, form data) is automatically imported and the current profile folder will be moved to the desktop to an "Old Firefox Data" folder.<br />
Installed extensions and other customizations (toolbars, prefs) that you have made are lost and need to be redone.
It is possible to recover more data from the old profile, but be cautious not to copy corrupted files to avoid carrying over the problem.
*https://support.mozilla.org/kb/Recovering+important+data+from+an+old+profile
You can try to restore the prefs.js file and copy this file from the "Old Firefox Data" folder on the desktop shortcut to the current Firefox program folder.
You can use this button to go to the Firefox profile folder:

Help with saving images Photoshop Elements
Hi, I am using Photoshop Elements 11 and Windows 8 or 8.1. Sometimes when I save images in PS E11, they do not save so that I can see the image as usual. Instead they save with either the Photoshop logo or the Windows Pictures logo. When I try to open them in Windows Pictures, I get a message saying something like "cannot open, wrong format" and I cannot post them onto the web either. What am I doing? Please help, thank you.
Hi Eeevanwok,
Please let me know if this is happening with particular file format?
And what all steps did you try from your end?

Please help my desktop images, wallpapers gone.
Please community i need your help. I restored my computer from Lion to lion, before i had Leopard and i had all my favority desktop wallpapers, for example aurora , earth horizon , earth etc.. When i installed for the first time Lion , i got even more desktop images for ex. Aurora at grey or blue colors those i loved so much . I am so new to mac's ok i did not even know where my folders were, i even wanted to get the same background images for me phone too ^^. But when i did a restore from Lion to Lion means that i erased(and i forgot to backup or search for the desktop images on my mac it was to late ) my disk and got the install all over again , all my desktop wallpapers were gone. Now please if possible for some1 to sent me if he got upgraded from Leopard to Lion and did not erased or kept a backup of desktop images, to simple sent me the folder with all the descibed images i mention, i would be very happy again thank you.

last night it did it again - powered off at home and sleeping when i got to the office.
any advice? -
Fundamental Question about Lightroom and saving images
I have to laugh as I get ready to pose this question because I've been working with the program for two weeks with Scott Kelby's book and with Lynda.com, and I'm still profoundly confused about what is happening to the photo. To wit: I open a camera raw file in lightroom and start playing with it, even taking snapshots at various stages along the way. If I don't export the photo to Photoshop and save it there, what becomes of these changes? Do they stay with the photo always? Do they disappear when I shut down the program? There's no SAVE button with Lightroom which just plain flummoxes me! Can anyone 'splain this to me, please? Thanks.
To clarify. Nothing happens to your originals. Lightroom stores the edits in a database (and if you wish alongside the original in a xmp sidecar file) as a set of instructions that the program uses to recreate the end product by following the instructions. These instructions are changed in the database while you're changing parameter values in Lightroom, so there is no need to save. Also, Lightroom stores a history of changes you did, so you can always go back. Both Lightroom and Adobe's camera raw plugin for photoshop can be used to follow the set if instructions. This way, you always get the highest fidelity image and you can always go back to your development choices without loosing any quality or having to dig up backups. Because of this, you can create multiple virtual copies with different development approaches without having to make a copy of the original and therefore saving you gobs and gobs of disk space. When you need a file for consumption such as a jpeg for a web page, simply export a copy, which burns in your development changes in a developed copy (just like printing a negative would have in the olden days) and trash the copy when you're done with it. You can always recreate it very quickly. This is a radically different approach than you're probably used to.

Help with saving images, icc profile?
Hi all, I just read an article http://everydayelementsonline.com/2011/07/web-browsers-and-color-management/ about web browsers and color management. I was going through and looking at how I save my images. In this article it suggests having the ICC profile checked when you save. I noticed when I go in to save from my mac all that pops up for me is "embed color profile: adobe RGB (1998)". I can't figure out why I don't have the ICC option.
I'm brand new to editing images and would appreciate any help I can get. I just want to make sure people are seeing what I think I'm actually editing if they're viewing from the web. I'd appreciate any help or tips, thanks!Andrea_GB wrote:

LOL !
That is the "ICC option". Adobe RGB is one of many ICC color space profiles.
However, for the web, you should really go to the EDIT menu and CONVERT to sRGB. (Do not use "Assign Profile". Use CONVERT.)
Then when you go to Save, you'll have the option to "embed color profile: sRGB…" (any such variant thereof)., which is another ICC profile and what all non-color managed expect to find on the web.

Shooting Tethered AND saving images to camera memory card?
While Tethered In Aperture 3 is there any way to leave/see the image on the camera memory card?
I review images while shooting as a client watches the images import into the computer.
This IS possible in Canon's EOS Utility but I do not see the corresponding preference in Aperture. Something like: "leave image on card during import."
Any thoughts? Thanks -- j
Canon 5D Mkii -- Aperture 3.1 -- Macbook Pro@e2photo -- yeah, I can't believe this functionality has disappeared. On the Apple/Canon side, it could be that the software cannot distinguish between importing all the images on the card vs. tethered and importing just one image at a time. I don't know.
@TonyGay -- thanks for the tip. I'll look into that software.
Also, I posted this on another discussion forum on flickr, and someone there swears he can get this to work, but I haven't been able to do so. He suggests looking at the preferences of the Camera's proprietary software (Canon EOS Utility). There is a check box for "leave image on card" but it does not make a difference in my situation. Knowing the finicky nature of all these connections, it may be that I have to do things in a specific order, i.e. plug in camera, turn on power, set preference, or vice versa. I'm still trying.
Cheers for the help -- jameel -
Open Word Doc and No Images Come Up
I am using Appleworks 6.2.9 with a G4 Tower running Panther. When I open up a MS Word document that has images in it with Appleworks only the text comes up. The images are not shown in the document. Any solutions to this other than investing in MS Office for OSX? Thanks.
ALWAYS the same response to the same question:
openOffice is a FREE clone of MacroHard's Office.
(runs on Mac with the X11 addition)

neoOffice is another FREE clone.

Problem opening program and opening a photo and saving a photo
I am continally getting the message "cannot open \device\hardisk\DR4"
I am lost as to how to fix this.
At this point I am ready to delete the program and reload it, but I am concerned that even if I do that, I will still get the same problem.
I have given up on trying to contact Adobe.This happens to me when I leave a card-reader plugged into a USB slot without a memory card in it. The solution for my situation is to either unplug the reader or put a memory card in the reader. If your computer has a built-in slot then I’m less sure how it works.

How to play/record at same time and save image from video

so here the code. all messed up. coz i have just completed it and havent worked on interface or formatting this code properly (didnt have much time). but hope it will help. ask me if u have any questions. dont want others to have those basic problems that i had to face.u did a good effort for the JMF beginners i appreciate that....thanks i lot....i need you help in a project in
which i have to connect to a d-link 950G IP camera and process that
mpeg-4 stream (i know there are some problems in JMF and mpeg4) and show it over applet of JFrame.

Loading, cropping and saving jpg files in Flex
I'm attempting to apply the code for selecting, cropping and saving image data (.jpg, .png) as shown on the web site:
http://www.adobe.com/devnet/flash/quickstart/filereference_class_as3.html#articlecontentAd obe_numberedheader_1
The sample application is contained within a class called Crop contained in the action script file Crop.as which begins as follows:
package
import com.adobe.images.JPGEncoder;
import com.adobe.images.PNGEncoder;
import flash.display.BitmapData;
import flash.display.DisplayObject;
import flash.display.DisplayObjectContainer;
import flash.display.Loader;
import flash.display.LoaderInfo;
import flash.display.Sprite;
import flash.events.Event;
import flash.events.IOErrorEvent;
import flash.events.MouseEvent;
import flash.geom.Matrix;
import flash.geom.Rectangle;
import flash.net.FileFilter;
import flash.net.FileReference;
import flash.utils.ByteArray;
public class Crop extends Sprite
My application attempts to make use of the Crop class by including the Crop.as file:
<mx:Script source="Crop.as"/>
in the Flex Component which needs it, and then calling the Crop constructor to perform the methods of the class
var localImage:Crop = new Crop();
localImage.Crop();
My application does not compile. The package statement (or the curly bracket on the following line) is flagged with the error "Packages may not be nested".
I have no idea why this should be as I cannot see any nested definitions anywhere in my application. The component includes the Crop.as file which contains the package and class definition.
Can anyone give my some guidance as to why this error is occurring?
Any help would be greatly appreciated.Hi Scott,
#1
that error is because "fx:Script" (or mx:Script) are intended to include part of Actionscript code - but not class defitions or blocks.
So if you are trying to include e.g. such class:
package
import flash.display.Sprite;
public class Crop extends Sprite
public function Crop()
super();
public function processImage():void
trace("processImage()");
compiler will immediately complain as you are trying to incorporate nested class within your application code.
#2
here is correct way (I think) to incorporate some class via mxml tags (here using fx:Script):
Using class sample above:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
xmlns:utils="*"
applicationComplete="completeHandler(event)">
<!-- util Crop will be initialized here as instance "cropUtil" -->
<fx:Declarations>
<utils:Crop id="cropUtil"/>
</fx:Declarations>
<!-- script where "cropUtil" will be used -->
<fx:Script>
<![CDATA[
import mx.events.FlexEvent;
protected function completeHandler(event:FlexEvent):void
cropUtil.processImage();
]]>
</fx:Script>
</s:Application>
But note that you could simply create instance of your class by direct import in fx:Script:
<fx:Script>
<![CDATA[
import mx.events.FlexEvent;
private var cropUtil:Crop = null;
protected function completeHandler(event:FlexEvent):void
cropUtil = new Crop();
cropUtil.processImage();
]]>
</fx:Script>
hth,

I would appreciate any help in saving images for dreamweaver.
The images are optimized in Photoshop and are saved as jpeg's with
a quality of 60. Image sizes are 400 by 600 pixels. When viewed on
the web, the images look fuzzy. Can anyone give me any directions?
Are the original images not saved in a high enough resolution after
editing? I would appreciate any help at all.
Thanks.
JCI had the same problem !!
When you export from fireworks 8, by shure you select in the
optimize panel
"JPEG - Better Quality" and JPEG in the second box. This
solved my problem,
and I hope your problem
