I have taken a jpeg map of Idaho and edited it as a PSD in Photoshop. I added dot locations with titles. I resized for the my website, and changed it to a jpeg. I moved to Dreamweaver and a map page. I then linked each location to a info page. I then uploaded it and it's on my site.
Question: How do I add more location as time moves by, or modify this jpeg??
What's the website address?
I'm curious as to how you're using these maps and locations markers. Sounds like a chore to maintain.
I suspect there may be more efficient ways of achieving what you're after without manually editing (in Photoshop) and re-uploading (with DW) map tiles.
