Your question: What are the requirements for vector images?

Answer:
Many of our illustrations will be supplied in JPEG format only, and will have 'JPEG' displayed in the type description.
We accept vector art in EPS or AI (Adobe Illustrator) format. EPS files should be compressed in a zip file before uploading.
We recommend you save your artwork in Illustrator 8 format for compatibility.

For all vector art, we ask you to include an image in JPEG format as well. Use the same name, but save as JPEG at the high quality setting for a large image (3600x5400 px; 12”x 18” at 300 dpi) in RGB colour mode. This way customers can choose which image best suits their needs, a vector based illustration or a JPEG format.
