trouble uploading

I went to the gallery & tried to upload a layout and it said "Your Image has been uploaded successfully!" Then it redirected me & there was no image & no image in the gallery--what's the problem?

Either the file size is too big, you selected the wrong file type (the psd/tiff vs the jpg) or there are too many characters in the description (the gallery gets kind of picky if you have a large description). If it's the latter, just leave the description blank, hit upload/submit and then update the description on the next page. HTH!
