Trouble uploading pictures

[Nicole4JK]

I'm having some trouble uploading pictures to my gallery. It just started happening recently, and I've never had this problem in the past. I upgraded my gallery to 1.4.8 thinking that would fix it, but it did not.

When I try to batch add pictures, it takes me all the way to the final step and then I get a red x instead of the OK. When I click on it, I get an internal server error. I am able to upload single files, though. I enable the debug mode if you want me to post that report. I honestly have no idea how to read it! Thanks for your help.

As you said I don't see any error on single upload ,
maybe it's a script time out issue , cause you have so many pics on each folder....
Is this happend always ?

Thank you for removing that login info! I wasn't thinking when I posted it here, obviously. This problem just started happening recently. I was able to get batch add to work just now by making my own "normal" version of the 1024x768 wallpaper that I was uploading. Does the problem have to do with the size of the picture?

big size photo => timeout issue

Try to increase php execution time
also try to upload smaller size and check ...

Yep, the smaller pictures seem to work! That must be it. How do I increase php execution time?

BTW, thanks for your help! I really appreciate it.
