Hi Vance,
Welcome to ShrinkTheWeb.
Q1. Is this service like "Thumbshots"?
A. Yes, only better!
We automate the capture of website screenshots but with much higher quality, scalability (capable of higher volume), and no extended downtimes like all the other providers.
Q2. Where do we embed the PagePix code for embedded requests?
A. If you are not using a plugin, then each case is different. It is up to you to figure out where to place the code. Our services are available for an hourly rate. Basically, though, if you already have code from a similar service, such as Thumbshots, then you would just replace the entire < img src > tag with the one we provide in the lobby area (when logged in). Aside from that, you may also find a specific integration in the forum posted by others. I've seen posts on vBulletin, Wordpress, Joomla, made a post on phpLD (PHP Link Directory), made a guide on PremiumPress (see PagePix Plugins Page), etc. Also notice that there is a "Search this site" at the top of every page where you can type in keywords that may pinpoint the relevant place in the forum or site.
We spent hundreds of hours documenting, so please take a moment longer to look around the site. We provide the tools to help you find what you are seeking. If there is nothing on the site to help you, we may be able to document for your specific case, unless it is considered a "billable consulting project."
Q3. Is it optional to link back to ShrinkTheWeb (attribution)?
A. Yes, it is optional but VERY MUCH appreciated if you enjoy the service.
Cheers!
Brandon
