Can not save jpeg file

I wish to capture jpeg images from my webcam and keep them in webserver so that live video can be downloaded. Because my adsl connection can upload @ max. 256 kbps, I can only transmit 2/3 frames per second. But for testing purpose on local machine I am capturing 10 frams per second ( seting timer for 100 milliseconds)
My program starts capture but after 2/3 or 5/6 frames it simply exts without giving any errors. I have tried to debug. But can not find which exception is causing the program to exit. Pl. help me diagnosing the problem :

Files are saved as 1.jpg, 2.jpg and so on. My another html page downloads these pictures @ every 100 milliseconds using javascript so that no seperate program is needed to show the video.
Pl. let me know how can I continue to save files .

Thank you so much catfoss.
I gave thread.sleep(60000) and was able to record more than 300 frames !. So, once again thanks a lot to pinpoint the error.
Now I am modifying the program and instead of using Thread.sleep I am going to use keyboard input ( Program will wait till Q is pressed. )
For thoe who are interested in viewing these pictures here is my javascript source, which show the live video :
<html>
<head>
<script type="text/javascript">
var no = 1;
var filn = "";
var myId;
function stopIt()
alert("stopping!");
clearInterval(myId);
alert("Interval Stopped!");
function startIt()
alert("Starting animation!");
myId = setInterval("changePic()",400);
//setTimeout(stopIt(),27000);
function changePic()
// alert("change time");
no++;
filn = no + ".jpg";
// alert(filn);
document.getElementById("b1").src =filn;

Can not open JPEG files and can not create JPEG files from other software

Can not open JPEG files and can not create JPEG files from other software (For example from Solidworks).
When I try to right click on a JPEG, a notice window appears written: "Windows Explorer has stopped working - Windows is
checking for a solution to the problem" and then the notice box disapears, the desktop appears and I can continue working.
From the other side - If I try to save as JPEG a screen of Solidworks (like a view of a part) the Solidworks falls but the JPEG
is created (I can see its name in the directory I created it).
I can open the JPEGS with the Paint software if I want but not with the Windows Photo Viewer.
I have the feeling that the Windows Photo Viewer disapeared from my computer - just a feeling.
I will appreciate your assistance.

Hi,
Did Windows Photo Viewer option appear when you right click the JPEG file and select open with?

The device is formatted for Windows, as NTFS. The format is readable, but not natively writable on a Mac. To write to the device, you must either reformat it (erasing all the contents) or install third-party software to enable write access to NTFS.

Can not save .gif files & My Virus protection software found a virus in your program

When ever I try to Save a .gif image, the upper bar populates with the image imformation, but the lower bar is completely empty, and offers no options. I am able to save all other types of images: .jpeg, .png, etc. Also, my virus protection software found a virus in your program files. Here is the result findings: Object: file Name: C:\Users\AppData\Local\Mozilla\Firefox\Profiles\9ifwxa87.default\Cache\2\B6\B7827d01 Threat: HTML/ScrInject.B.Gen virus Action: unable to clean Also, Firefox loads & runs really slow and sometimes fails to load at all. I have plenty of memory and hard disk space. Can you help me with these problems? I am expecially worried about the virus issue as I have a really good anti virus program & this is the 1st virus it has been unable to block or clean!

Jim there have been other postings about the new Adobe applications being misidentified as possible viruses. Please contact your virus protection company so they can update the definitions appropriately.

Let us start from the beginning.
It has been established that you have Premiere Elements 10. On what computer operating system is it running?
There has not been a File Menu/Export/Movie export opportunitity in Premiere Elements since version 7. We are not up to version 12.
For Premiere Elements 10, your export opportunities are all in Share/ including one for Computer. Under Computer there are several choices. The ones that you see are Adobe Flash Video, MPEG, and AVCHD. The others you have to scroll down to. And those choices are AVI, Windows Media, QuickTime, Image, and Audio. You do not have to use the scroll bar for this. You can click on Adobe Flash Video panel to get it to turn black. Then use the down arrow to go down the list and the up arrow to go up the list. Once you get to a category, you can select a preset and go with it or customize it under the Advanced Button/Video Tab and Audio Tab of the preset.
If you post the properties of your source media that you want to try to match in the export, I would be glad to suggest the exact settings for you.
We will be watching for your follow up with details.
Thank you.

Add On...The Premiere Elements 10 File Menu is for more than Saving, just not exporting. One of the key features that can be access there is the Project Archiver. More on that another time.

"Can not Save file name " InDesign CS6 - Cloud---WTF!

Hello anyone
This new Cloud Adobe CS6 is SO buggy.
not my first issue with it...
I am using
Cloud version of - but locally installed
Trial version of CS6 InDesign.
iMac - mountain lion 10.8.1
i7/12Gig RAM. SSD, and 1 T platter drive.
Anyway-
After many HOURS of InDesign work.
Many pages, lots of stuff.
I exported my work as PDF to send to my boss. Worked fine.
But I can't save the working file.
All Save menu items are grayed out.
The astericks is there in the window title.
When I just close the file- I am prompted to Save the file or lose my work.
I hit Save and get window
"can not save filename"
with no error code.
NOTHING!
This has happened twice. First time not a lot had been done to the file.
So I just re-started the iMac
This time I stand to lose some real work here.
Does this happen if I just use the free version!?!?!?!?
I will happily pay after my trial but if this is what the new CS6 has in store, then screw Adobe.
Can anyone help me???

There's no difference in fuctionality between paid and free versions.
There are two things worth trying, if you haven't already closed and lost the file. The first is to export to .idml, open that and see if you can save it with a new name: Remove minor corruption by exporting
The second is riskier as it depends on ID's amazing file recovery after a crash. If the method above fails you haven't got a lot to lose, though, so here here's the next thing I would try:
Force Quit Indesign. See Replace Your Preferences and use the manual method to replace the InDesign Defaults and InDesign SavedData files (and while you're at it, make a backup copy of the InDesign Recovery folder). Also see Adobe Forums: InDesign crashes at startup and delete the additional files in John's post. If you need to delete or copy hidden files and don't know how to access them, see Access hidden user library files | Mac OS 10.7 Lion
When all that is done, restart InDesign. With luck, autorecovery will open the file again with not much missing and you can try to save it.

I get message:can't save library file not enough access privileges.Don't understand what this means?

I get message:"Can't save library file. Not enough access privileges" .Don't understand what this means. No visible effect that I can see now.

Classic example of why you should save your workm in progress...just hit Ctrl+s to do it on the fly.
Yes I know. But it is the first time I work with Photoshop on such a big project and I thought it would be more stable.. Do the newer versions manage the memory better ?
You can shrink your image down which will make it smaller enough to save
Not enough memory to resize the image. And in the manipulation, it would corrupt some of my layers..
you can try to save as a diffeent format
I could succesfully save in Bitmap format. But I lose all my layers info..
The making loads of screen shots would be good if it wasnt really an
option seeing as it would use even more memory to do that then put the
image together out of the screen shots.
I made screen shots without any problem. I saved them through MS Paint without any memory problem, while Photoshop in parallel was just used as a static image for snapping...

CS6 can not save files over 2GB???????

I need to make a giant poster at 6ft wide x 5 ft tall. I created a blank document in CS6 at 200ppi. I created some text, and imported a couple of 25MB images. I am unable to save the file as a .PSD because it indicates that PS can not save files over 2GB.
1. How did this file grow to become over 2GB?
2. Why can PS not save a .PSD over 2GB?
3. What do you do if you need to create a large format print such as this?
Thanks in advance.

Very true.
However, Jeff knows exactly what he's doing and he's very, very good at it. If your image were fortunate enough to end up being printed by Jeff Schewe, he'd be able to tell you exactly what kind of an image file he wants from you.
Always check with the printer.

I have an iMac(mid2010) running Pages v5.5.1 on OS X 10.10. Why can I not save or share documents. The error message is You can't save the file "TEST.pages" because the volume is read only.

I get the same message when using Numbers so I presume it is a OS problem

Some of your user files (not system files) have incorrect permissions or are locked. This procedure will unlock those files and reset their ownership, permissions, and access controls to the default. If you've intentionally set special values for those attributes, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it, but you do need to follow the instructions below.
Back up all data before proceeding.
Step 1
If you have more than one user, and the one in question is not an administrator, then go to Step 2.
Enter the following command in the Terminal window in the same way as before (triple-click, copy, and paste):
sudo find ~ $TMPDIR.. -exec chflags -h nouchg,nouappnd,noschg,nosappnd {} + -exec chown -h $UID {} + -exec chmod +rw {} + -exec chmod -h -N {} + -type d -exec chmod -h +x {} + 2>&-
You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign ($) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1, if you prefer not to take it, or if it doesn't solve the problem.
Start up in Recovery mode. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open. In that window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button
Select
 ▹ Restart
from the menu bar.

Downloaded aquarium screen saver. Says can not find Resource file

Downloaded Auaruim screen saver, installed it, but can not find Resource File.

>Funnily enough it loaded on an old pc easily!
Hi
This means that drivers are ok and there must be something wrong with the system preinstalled on Equium U400.
How did you proceed?
Its important that you would NOT connect the Dynadock to the notebook before the drivers and software installation has not been finished.
Therefore you have to install the software firstly. Then after new reboot connect the Dynadock to the notebook and the installation would finish the next steps.
