Do you still have EQ installed? If so, take a peek in the UI folder and see if there is an images subfolder, and check whether you have the image files for that target ring.
EQ2 uses two files for the ring target:
ring_target.dds and
ring_target_con.dds. If EQ1 uses the same ring target files, you might be able to just drop them in, otherwise, if you can post the EQ1 target graphic files someone could work from that (i.e., not a screenshot, I mean the actual files EQ1 is using).
The image files used by the EQ2 UI are all in DDS format, so the be able to look at the actual image, you may need a special viewer. I use
Irfanview to preview them, if you want to manipulate a DDS file you can use the free tools
Paint.net or
GIMP (GIMP needs a
plugin). You can also get a
DDS plugin for Adobe Photoshop.
