Before scanning an image the required resolution and image mode must be determined.
1. 300 dpi: used for commercial printing of books, glossy magazines and brochures
2. 150 - 200 dpi: used for laser and inkjet printers
3. 72 - 96 dpi: used for e-mail attachments, the web, powerpoint and multimedia.

Scanned image of disc with the resolution of 75 dpi. This resolution is ideal for blogs. The larger the resolution, the larger the scanned image will appear. 
Photoshop's save for web & devices feature
Adobe Photoshop's 'Save for web & devices' feature allows one to optimise their photos for websites without affecting how an image looks. Slowness in the loading of websites are generally caused by images. To save an image through this feature you use File>Save for Web & Devices. Upon clicking this an options panel appears with a preview window which allows you to resize the image, select image type and alter the resolution. If you were uploading the image onto a blog I would recommend setting it as a JPEG.
