Need a simple program to add captions to lots of images (Several 1000 - for a hobby website). Some will have the same caption, so copy and paste are a requirement, but may need background colour changes, depending on image colours in the caption placement area.
I use OSX 10.9.5 and I have tried Preview, but it does not have the facility to style text, BOLD and Italic.
I am looking for a solution, in which I can quickly make these captions.
I have Affinity Designer and Inkscape and Pixelmator, which can do this but they are very much overkill, for a relatively simple task. Preview would be fine if it met my requirements.
Annotate would appear to have done what I want, but it needs a newer version of OSX and Napkin seems a bit expensive for what I need.
Any advice appreciated.
