err... another thumbnail question :/

[unseen]

first of all i have to say pixelpost is the most genius tool i've seen for photoblogging. i'm in love.

i had a few bugs at first but it was all my own fault.. but this time i really have no idea what happened. i haven't changed anything except that i put in a new template yesterday, but i uploaded a photo after that and it worked fine. today i went to upload another photo and it wouldn't create a thumbnail. this is the error i got:
Warning: imagejpeg(): supplied argument is not a valid Image resource in /home/unseenze/public_html/pixelpost/includes/functions.php on line 92

Warning: chmod(): No such file or directory in /home/unseenze/public_html/pixelpost/includes/functions.php on line 94

Warning: imagedestroy(): supplied argument is not a valid Image resource in /home/unseenze/public_html/pixelpost/includes/12cropimageinc.php on line 104
does anyone know what i might have done? any help would be really great... thanks!

well once again i seem to have fixed my own problem. i still don't know what the problem is exactly, but apparently it was something with the picture i was trying to upload. i tried a different picture and it was fine. *sigh* feel free to delete this post, heh... sorry!!

which kind of image did you try to upload?
was ist JPG? produced by which camera, edited with which tool, saved in which JPG-standard?

i'm pretty sure it was a jpg, but i use paint shop pro so it may have saved it as .psp. everything else was the same as every other picture i took and uploaded though. i'll have to go back and look at how i saved it. thanks! :]
