Hi
i dont know anything in .Net ,C# but i know images with vfp codes only-I think your related job can be done only with vfp9.

*strconv(13): Converts single-byte characters in cExpression to encoded base64 binary.
*strconv(14): Converts base64 encoded data in cExpression to original unencoded data.

local m.myvar   &&encoded 64 obtained with strconv(filetostr(getpict()),13)
text to m.myvar noshow

thisform.image1.pictureval=strconv(m.myvar,14)  &&restore image from blob on a form (rendered with gdiplus)

try this code on a form (1 button+image control) : you can see image restored in image control.

you can build a vfp report from your images and preview/print easily.
