In QC I would do one of two things, either
a) inside an iterator load individual images from a structure and increment the X-offset so they run from off-screen left to off-screen right using a billboard patch inside the iterator macro ( with a set amount of offsetting for transparent space between the thumbnails).
b) using a JS patch or in an iterator to control a loop to add single images to a collective image making a horizontal row of thumbnails with space between them into a single image.
How would I go about doing this in Vuo. Should I just wait for a iterator node in Vuo or are there other ways?
Perhaps I need a Transform Image patch to offset the origin point relative to image so that when I use the Blend Images node I can place one beside the other with space between.
Here is a link to a QT movie explaining the concept visually.
