Hello again,
The free app I mentioned that works well to add text to an image is called 'Phonto' for iPad. I have powerful photo editing programs for PC and Mac (Adobe and Aperture), and use the free Picasa app for covers, but none add the text as crisply as Phonto I find. It's worth a try, though I don't if a computer version exists, or if it's tablet only.
You'll notice a slew of votes for "Caveman Executive" from me, but as of yet no comments. I had a little time to read yesterday, so I zipped through several chapters. Very enjoyable, the dual storylines have me hooked. I decided to try out this method of reading it all, then commenting after I get a feel for the story (and some evenings my aching wrist needs a rest!). I shall comment as I always do, never fear...
