Image Browser - SDK, ActiveX Interface, or what

I am writing an Image Browser using Visual Foxpro and am looking for an ActiveX or DLL interface that will read images files and turn them into thumbnail and/or small JPGs. Short of requesting to download the SDK... I am not finding any documentation on whether it is possible to access the Adobe Photoshop Image activeX control that I find installed on my PC by Photoshop. Please help me with this very basic question.

Thanks, Alan
