I suspect this just isn't practical, but.. I was watching the "merge images" video and it's use of the Google Transparent image server background, which struck a note for a possible solution in a current 8 project*. I followed the detailed examples to create a new data source using the Manifold 9 driver to a 9 project with a Google transparent image server data source (see screenshot). Followed by opening the 8 project and selecting the resulting Machine Data Source via the Database Console and choosing "link" per this example - second screenshot. Something's happening in the background but I suspect, if anything, it might be trying to download the lot, at best.

I appreciate the example deals with drawing tables rather than web server image tile tables. Is what I have attempted even plausible?

I too am feeling much more comfortable working with 9 as time passes.

*It's a project which still needs to split areas with lines, distribute numeric data proportionately on area and do a table join which currently yields the "invalid Object Reference" discussed in this thread on re-opening.

Trying to bring raster data from 9 to 8 via ODBC won't work, unfortunately, because 8 doesn't understand the tile format used by 9 and because 8 won't be able to organize individual tiles into an image. You will just get a table with X, Y and some binary values.

You have to either export the image in 9 / import it in 8, or use a database like Oracle which can store rasters that 8 recognizes.

However, for Google images specifically, you can use an image server in 8.

We will fix the error on opening the file that you reference. After we do this, let's continue with the split / distribution proportionally to area (this isn't terribly complex).

Thanks for the explanation and alternative, appreciated. For a "transparent" web image in 8, WikiMapia still works.
