I know on my VPS there is a file/folder limit. It's a huge limit but there is a limit.
The down side of this is that it places an unnecessary load on the server. Take for example a page of thumbnails resized by the server from larger images. Server resources are consumed for every image resize which needs to be performed as the page loads.
You don't have to serve them dynamically and I'm not even sure why you would unless it was special case like you're serving a captcha image.
If you can't do it server side use a tool like irfanview to batch resize and upload with FTP.
Since you mention artists one thing to be aware of is EXIF/IPC is typically stripped using the GD library which is standard way to resize. You need to use Imagemagick or additional PHP libraries to keep that information.
