In order to submit an image for inclusion in the Tyler art gallery, you must first read and follow the rules and guidelines listed below.

• Acceptance: Submissions may be rejected and may be renamed or otherwise edited at the discretion of the curator unless you expressly specify otherwise, though that may affect the acceptance of your submission.
• Removal: Superliminal Software reserves the right to remove any previously accepted images at any time at the discretion of the curator with or without the artist's consent. You may always request removal of an image of yours that was previously accepted.
• Authorization: If you are over 18 years old, you must be the creator of any image you submit. You may also submit on behalf of a child or other person under 18 if you have their permission. In all cases the artist's and submittor's names and email addresses must be included.
• Derivative Works: By submitting an image, you vouch that that image is not a copy of or a derivative work of another artist unless you have the express permission of that artist. In those cases, your submission must include the name of the original artist. You may, however, submit an image which is based on another image already published in the Tyler gallery if your image is substantially different. In that case you must include a description (see below) that includes a citation of that image including the artist's name and the URL of their image's gallery page. You may include HTML hyperlink tags in your text if you have permission to create such links. You may always link to other Tyler gallery pages.
• Disclaimer: You must agree to the public publication of your art. Superliminal Software takes no responsibility for the unauthorized use others may make of your artworks, and takes no responsibility for validating the right of the submittor to publish such artwork.
• Size: Images may be of any size, though roughly 500x500 is typically a good size.
• Image Format: Images must be in either PNG or GIF format. PNG format is preferred especially when it is smaller than the equivalent GIF version.
• Email Format: Do not send email in HTML format. The published web pages are generated programmatically. Only plain text email with image attachment(s) should be submitted.
• Palettes: You should use the smallest practical palette size, preferably 255 or fewer colors.
• Colors: White backgrounds are preferred but feel free to change colors using other image processing programs.
• Post Processing: You may alter your images using other image processing tools but the submitted image must have been substantially produced with the Tyler Applet.
• Dates: If a copyright date is not specified, the date of the email message will be used.
• Categories: Your email should specify the gallery room you feel is appropriate, especially if the symmetry type is not obvious.
• Descriptions: You may attach optional descriptive text or caption to accompany your image.
• Image File Names: You may name your images however you like though names should not be excessively long or short. Only letters, numbers, and dashes should be used. Do not use blanks or periods except for the dot before the file extension. The file name will be used as the title of its gallery page.
• Data Files: Attaching polygon data files are appreciated though not required. Note that if you use the Tyler applet often, you will probably prefer downloading the application version which supports additional features including the ability to save your polygon data for future editing or rendering.
• Thumbnails: Attaching a 200x200 thumbnail version of your image is appreciated. This may become a future requirement, so including one now will increase your chances that your image will remain in the gallery.

Thank you for your submissions.
