We FTP'd 7000+ images to the uploads folder using a standard linux install and Plogger did not import any of them. Then we tried only uploading 400 images, and Plogger only recognized 9 of them. All were standard JPG format.
What can we do so Plogger will recognize every image?
There are limitations to how long PHP scripts are allowed to execute. You can make this time as large as you want if u control the linux server, otherwise u must do the uploads in groups of about 10 depending on the size and resolution of the pictures. I've found keeping the images at a max size of 1MB and trying 6 at a time works fine, but for large uploads like your describing, there's gotta be a way to customize Plogger to automatically split the upload into steps (i'm thinking a javascript function that calls the upload script with only groups of 5-10 until all images are done)
Well we've tested it before on a dummy site and uploading the 7000+ images worked...Also, uploading 10 at a time would take a VERY long time...we're also doing it through an FTP, not the PHP script.
You are uploading through FTP, but Plogger has to execute the PHP import script in order for the images to show up in the albums, so you would run into the PHP limitation on execution time for the script.
