For some reason my resize & thumbnail function only works with one file.
When I try to upload more files, for example 3, it only processes the first file correctly.
It saves it in my directory, resizes it, puts on a watermark and inserts the paths into my database.
The second file is only saved and resized, no thumbnail is saved and it's paths aren't inserted into my database.
The third file doesn't get processed at all and the page won't return to it's original (which it should, and display an array of the images that are uploaded).
If I comment out the thumbnail function so that it only runs the watermark/resize function, it only processes the first two files and will only put the first file into the database. Page won't return to it's original state.
If I comment out the watermark/resize function, so that it only runs the thumbnail function, it only processes the first file untill the thumbnail function (so it saves the original but won't resize it to a thumbnail and won't put an entry into the database). Page won't return to it's original state.
If I comment out both the functions, it uploads the 3 files correctly and saves the paths into the database. The page returns to it's original state.
What am I doing wrong?
