You have two options: scan your art or take a picture of it. Scan your art Either you have a scanner at home and it is large enough to handle your artwork, or you can use a scanning service (in the US most Office Depot and Staples stores can scan for you, in France you have Copy-Top stores or the likes). You should scan your art to a 600dpi 16-bit color RGB TIFF for archiving purposes. This is a large enough dpi that you can use the scans for print publication (in case your art is ever needed for one of the prestigious Artist Editions books from TK or Gallery Editions from Graphitti Designs!) You can then create a copy of your archival TIFF and downsize it to a 150dpi JPG for posting on ComicArtFans, 2DGalleries, or social media. It is usually better to scan in color, even for black & white comic art, to capture details such as page quality, pencils, blue lines, etc. Take a picture with your cell phone Modern smartphones have good cameras. You don't have any limitation on the artwork size, and "document scanner" applications make it easy to crop the image (e.g. remove any distortion of the page and make it "square" again) and enhance colors and sharpness. Comic art collectors usually use CamScanner or Microsoft Office Lens: CamScanner for Android / CamScanner for iPhone Microsoft Office Lens for Android / Microsoft Office Lens for iPhone Be careful of lighting when taking your pictures - try to keep brightness uniform on the whole page and avoid shadows or overexposure.
