I went back and took your advice on some of the image size parameters. Yet it is Abantecart and not my server, hosting, nor Internet connection. The issue was the scale of the image not the size as in Mb or Kb. I had uploaded larger files in memory size with no issue. Yet despite these other images going up with smaller memory size the scaled size just tipped over what AbanteCart could handle apparently. Such a simple issue such as the image scale I overlooked. I am working with art which when people see you want them to see as much detail as possible. So if I continue down this path I will have to standardize to this limit which would work.
As for my hosting service I have loaded massive files never with an issue. My work depends heavily on the graphic visuals in what people can see. I have programmed not only my site, but also machinery to interface with software via linux to be able to carry an accuracy to within .003 of an inch physical output. So Im not someone whos unfamiliar with many different kinds of issues. The more complicated stuff people normally ask questions to were not that big of a deal interfacing with my hosting and so forth. This one made me scratch my head.
Is there documentation as to the file parameters that the database can handle on any given file such as size in memory and also scale of various types? Videos included, or even the file size of pdfs?
