Okay, after perusing the net for long enough to be very frustrated at Adobe, it seems there is no plugin that will just do RTL in photoshop. There is one for arabic, but I’m not sure that it is what I want (it doesn’t actually do the text in RTL, it only displays it as such using raster or s/t), and I don’t feel right donating to the software author (who requests a donation for usage) for personal reasons. The lack of RTL plugins seems to be because of the Adobe PS ME (Middle Eastern) edition of Photoshop (CS5), offered by Winsoft, for a small fortune. ($1350 I think I saw? When the whole CS5.5 is only $1800 or so....).
As I do blocks of hebrew and not that much, I was going to stick with what I did before (hurt my head and type backwards) but here are two tools I found that may help me out:
http://bitofgold.com/converter.php
http://www.flipmytext.com/textreverser.html
Both of these tools will allow me to write the lines out, and then have the characters flipped without hurting my head - I’ll still have to go a line at a time, but I can live with that.
Another option I’m going to look into, is I downloaded a copy of GiMP for Mac; if there is pretty good editing allowed in there, I may just do the designs in there, or rasterize the effects from Photoshop and drag them in. Or type the text out with typography, and rasterize the layer and send to Photoshop. Any would work....not my favorite solution, but an acceptable work around....Thanks for the help Susan!
