Changing JPG to JPEG or GIF & resizing

I'm trying to post my pictures on a website, but the're in JPG and the website only allows JPEG or GIF. How can I change the images, and how can I make them smaller, i've tried making them smaller to export, but they still end up big, so I need another option rather than exporting. Please help.

Welcome to the Apple Discussions. To resize for other applications just select those you want to resize and use the File->Export->File Export route. There you will have the option to select the size you'd like.
As for the JPG vs JPEG, have you tried submitting a JPG file? Those two extensions are the same and can be used interchangeably. The JPEG is the more formal representation of that format. If the simple JPG extension is rejected you can use R-Name to batch change the extension to JPEG before you submit them to the site. You'll have to do that after you export from iPhoto.

Mail.app changes .jpg to jpeg

Sometimes Mail.app insists on changing the extension of a file saved with ".jpg" extension to ".jpeg", which causes some recipients' Windows systems to refuse to open it. This happens even though the "Send Windows-friendly Attachments" is checked. Why does that happen, and what can I do to prevent it?

By default the mail app changes an image size (makes smaller) when emailing.
If you download it directly it will stay the same size.
In pre-OS3 version it woudl resize smaller images up. i think that is fixed with 3.0
iPhone also reduces on export to the iPhone if an image is deemed to large for the iPhone
If you need to email at full size or transfer via server to another phone then you have to do it yourself.

Why do I have to change .JPG to .jpeg?

Every time I email a photo from my iPad Photos app and receive it in Outlook on a Mac running Mavericks, I get a warning saying - You cannot save this document with extension ".JPG" at the end of the name. The required extension is ".jpeg" This seems very strange to me. I have loads of pictures with the .jpg extension. If I have to have 2 different extensions depending on how the pictures arrive on the Mac it makes searches more complicated.
Does anyone else get the same message in a different mail client, such as Mail?
Is it an Outlook problem perhaps?
Do the upper case .JPG letters make a difference in which case why is the iPad using upper case for the extension and not the file name (photo.JPG)
Baffling. any thoughts extension gurus?

He used capitals . . .
Nope, that's not it, either. Just figured out the trigger is how you save the attachments.
I've always just grabbed them at the top of the email and dragged the attachments to the desktop. As shown here:
Screen grab doesn't capture the mouse, but if you simply grab the attachment name (highlighted when clicked on) and drag it directly to any location, it saves without issue. BUT, if you use the save attachment command (Command+E), that's where the bug is. It will add .jpeg to the name, even where it already says .jpg, and you can't stop it from doing that.

To be perfectly clear, you CAN use the Extra Plug-ins Folder specification to point to a separate folder you've created where you have put ONLY your 3rd party plug-ins. It can be a neat way to help organize plug-ins, especially if you don't prefer to copy things into your Photoshop installation area.
Just don't point it anywhere in the installation area for another version of Photoshop.
The basic problem is that many folks, in trying to save time, choose to point their Extra Plug-ins Folder setting to the plug-ins subfolder inside their old Photoshop installation area, thinking that will just make them all available to the new version. The key thing is that the old versions of Photoshop ALSO had put their own Adobe-supplied plug-ins there. The conflict arises when the new version of Photoshop starts and tries to enumerate the plug-ins, including those found in the Extra Plug-ins Folder, it finds overlap between its own plug-ins and the old ones it finds there.

Jpeg and gif images are not fuzzy

Look at the bottom of this page as well [http://carlback.blogspot.com/2007/12/apex-and-3rd-party-js-libraries.html]

Carl,
the only drawback with #WORKSPACE_IMAGES# and #APP_IMAGES# is that it doesn't get cached by the browser. So each page request will transmit the hole file again. A caching option for the "Static Files" in the Shared Components would be nice :-)
About lazy loading with the #WORKSPACE_IMAGES#. I could think about a mod_rewrite rule which translates the additional file request of the JS library into a valid request for APEX.
Carl Backstrom
In 3.1 we emit a last modified header now for uploaded files so that should help with browser caching.
I wonder if anything's changed since then.

How to change the color of 1px_trans.gif image of interactive report

Hi All,
Iam using interactive report in apex3.2
I need to change the color of 1px_trans.gif or remove the image in search tool bar
where we can change.
pls tell me .......
Thanks & regards
Balu..

I need to change the color of 1px_trans.gif or remove the image in search tool bar 1px_trans.gif is transparent and doesn't have a colour. It is used as a shim image—an outdated way of controlling the dimension(s) of some element(s). It's intended to be invisible. Giving it colour will cause it to become visible, resulting in all sorts of unexpected and unwanted lines (or worse, solid areas of colour) appearing throughout applications.
What do you think you want to do? (Whatever that is, it will almost certainly not be achieved by changing the colour of 1px_trans.gif...)

Jpeg to gif ( too many color exception !)

Dear all :
I want to convert a jpeg file to gif file (no need to animation's one ) using java . I have found a source program (GIFEncoder ) that convert the image to the gif file . But when i using the class to convert a jpeg to gif, a ' too many color exception ' has return . It is not diffcult to think why the exception happen , it is because the jpeg is always represent in true color (24 bits) , while the gif can only display 256 color (8 bits) . so , i have no ideas that how to create a 256 color jpeg using java ? because the JPEGEncoder package provided by sun will create a 24 bits jpeg file .The JAI can't create the gif files as the animation features of gif files .
So anyone can teach me the ways of how to create a 256 color jpeg using java , or a suggestions that create gif file using java ?
Thanks in advance !

Here's how I do it (it's not based on a color theory or anything, it's just the first thing that came to my mind when I needed this functionality in one of my applications):
I set up a table with the 256 most frequently appearing colors in the image. Sometimes, these colors are too similar, so I use a little algorithm that makes sure that the colors are satisfyingly different. The algorithm takes a parameter (the color dispersion parameter) and works according to the following pseudocode:
for all colors in the palette do:
differential = 0;
differential = abs(oldColor.red - newColor.red) + abs(oldColor.green - newColor.green) + abs(oldColor.blue - newColor.blue);
if differential < color dispersion parameter
don't add new color
If the new color passes this test, it is added to the palette. Depending on your needs, you may want to let the user select the degree of "color dispersion". If the palette doesn't contain 256 colors after this first pass, I decrease the color dispersion parameter by one and loop over the colors again (keeping the palette from the first pass of course). When this parameter reaches 0, there must be 256 colors in the palette, or the picture wouldn't need to be converted.
Then make an IndexColorModel from your palette data and set up a MemoryImageSource. From this you can create your image and do whatever you want with it.
Hope this helps!

When I move a RAW file from IPhoto to my desktop or Photoshop it changes to a jpeg and reduces in size. How can I get the Raw file across?

When I move a RAW file from IPhoto on my macbook pro to desktop or Photoshop it changes to a jpeg and reduces in size. How can I get the Raw file to move across?

I create separate folders based on the year and then the actual date of when I take images. You can make those folders anywhere on any hard drive that is connected to your Mac whether internal or external. I also use the Photoshop Photo Downloader that is included with Photoshop/Bridge and it will create the date folder so all I do is create a Year folder.
Open Bridge or click on the Bridge icon in PS and in the File menu item in Bridge select "Get photos from Camera". It can be a camera connected to your Mac or a memory card from a camera. A window will open and you then select the camera or memory card. Set the location they will be downloaded to, just the folder and you can Browse to a folder that you created, then in the "Create Subfolders drop down select what date stamp you want to use or or custom name or not to create subfolders at all.
I've never cared for iPhoto one bit. I tried it but found it way to restrictive. It likes to have full control over how you interact with your images.

IPhoto won't import jpeg or gif, or any common photo types, from backup CD

I recently had my hard drive replaced. I had backed up all of my photos on a CD, but iPhoto gives an error message when I try to import some of the jpegs and gifs to the new HD: "The following files could not be imported (they may be an unrecognized file type or the files may not contain valid data". Is this a software issue?

Back up your iPhoto library, Depress and hold the option (alt) and command keys and launch iPhoto - rebuild your iPhoto library - start at the first option and try each one in order

Convert JPG to 256 color GIF

Is there any existing class file to convert a JPG to 256 color GIF?
I tried some free src from there:
http://www.geocities.com/marcoschmidt.geo/java-image-coding.html
But seems that all throrw exception if the image got more than 256 colors, since my server is not using JDK.1.3x, so I can't use Java Media Framework.
Any good suggestion?

GIF files only support up to 256 unique colors, so you need to reduce the number of colors used in your images -- a process called quantization. This will result in a degradation of quality, but the result is usually acceptable.
See the discussion here for a link to a decent quantizer:

Change RAW to JPEG on Card

Hi youall, I want to get thumbnails from my compact card inserted in the printer but I do most my pictures in RAW and the printer doesn't recognize a card with RAW pictures on it. I would be uploading first to my computer in order to keep the originals in RAW then change RAW to JPEG on the card and put it in the printer. Is this possible?
MartyL

Barbara, I'm not even sure the RAW+JPEG will work for Marty. I assume it depends on how the JPEG is stored on the memory card. In the case of early Canon G series cameras, the JPEG was 'embedded' and had to be liberated using Canon-supplied software or BreezeBrowser; you couldn't see a separate JPEG file on the card. I haven't looked lately at how it's done. It will surely be different for other manufacturers....

Look to using jQuery instead of Flash. There are a variety of redy-made solutions available, just search Google or visit the Dreamweaver forum and ask there.
