Thread:Extension talk:MultiUpload/Select more than one image at a time/reply

You're right, it's a pity that no adequate solution has been found for what seems like a basic need for many users. For similar functionality, there is Extension:SpecialMultiUploadViaZip, but it was last updated in 2007, so not very likely to work with current versions of MW (correct me if I'm wrong though). I don't know about Extension:UploadWizard, which requires ImageMagick and I don't have shell access to install it.
