That's great and it works - presume the same for any other image format?

Now the second part of the problem - now I have the image in my vfp table I want to transmit the table to my Clients so they can at their end extract data and images for whatever purpose thay need - don't ask me why as the explanation would take too long - but I have been asked to transmit as a single file rather than a data file and a separate image file

Most dont use XML - if I transmit the file as HTML how do they extract the image - or is there some other way of transmitting the file to make it wasy for the recipient to extract the data and the image separately?

Thanks for your help

Colin

>Keep in mind that bmp is pretty much the only not-compressed format out there (one of the reasons why in the nineties and later the hardware sellers were smiling when you said you wanted a machine to run Windows - it took MS some time to confess there are JPG, GIF and PNG). Also, for the same reason do not use general fields, because they contain a preview of the actual content in... bmp format. Often a 5k jpg makes for a 500K general field, because it represents a large bitmap (low in detail so it compressed well).
