After checking the permissions on the folder, my user account was listed there with the correct permissions (read, write, execute). The Products_Insert.php page is putting the images in the \images\Upload folder, under my www directory.
In that folder, there are about 16 image variations (all with a different number at the end) from todays date. So that is showing me that they are going to the correct folder that is stated in the products_insert file.
So I deleted them all, just to see what would happen. Now, the only error I get is:
Fatal error: Call to undefined function WA_DFP_Resize() in C:\Inetpub\wwwroot\HCRESELLER\acalamed\acalamedical.com\www\DB_Admin\Products_Insert.php on line 76
Here is line 76: WA_DFP_Resize($WA_DFP_UploadStatus["WA_UploadResult1"],400,400);
When I looked back into the \images\upload folder, there aren't any images there now.
