PNG images as attachments

I’m trying to reply to a post in the install/boot forum, and need to attach 2 bootchart png images, but the box at the bottom of the screen says “You may not post attachments”.

A previous reply does have a png image attached.

Could someone tell me the best way to do this?

Thanks

Actually the best way is to use something like
ImageBam - Fast, Free Image Hosting and Photo Sharing

Ditto what caf4926 says…there’s lots of image hosting sites available. However, notice that the image in the thread you are referring to is not attached to the message, but rather is URL linking to an external image on the openSUSE site (not the forum site).
