A summary of the rules, the observance of which is the basic prerequisite for approval and launch of banners using the advertising system.These rules will serve as guidance for banner creation. Their observance simplifies the whole process of launching advertisements. Exceptions will be handled individually. 

If not otherwise specified, these rules apply to all banners

1. The advertisement must not be too aggressive, meaning shivering or blinking - banner that in a very short time period - less than 1 second - changes colours, titles or any other graphic items (those can disturb users from site work) violently, we consider as an aggressively blinking banner,
2. The advertisement must not contain vulgar words or images or other features in bad taste,
3. The advertisement must not surpass approved data limits,
4. The advertisement must be of the right size for the required position,
5. The banners must be sufficiently visually different from the website content throughout the display period (animation) i.e. the border, background colour, etc.,
   
6. The advertisement must not contain operation system control items and must not look like a system message,
7. The advertisement must not contain sounds, except the video banner,
8. The advertisement must not feature Butkaj.com brand name,
9. The advertisement must not contain form to fill in,
10. Flash banners must have a fixed background color (e.g. photo, color area) as they are inserted into pages in the transparent mode,
11. For special advertisements, cooperation with Butkaj.com experts is essential (the representative handling the advertisement will provide contact details),
12. Flash banners must not overload the CPU,
13. Creatives in HTML format must not go over the data limit for the specific format,
14. All the flash banners located on websites must be set to "_blank,
15. When displaying using a JavaScript interface, it is not permitted for any external codes to use the IFRAME element on any level,
16. External codes must not cause web page errors (display errors, JavaScript errors),
17. External codes and their creatives must not go over the data limit for the specific format.

1. Missing borders
The Flash creation background is too light or the border is incomplete (usually the frame only goes along the left and upper sides of the banner or vice versa). Or the frame is completely missing.

Solution
Create a 2px line with banner dimensions (e.g. 120x600px) and then centre it. Subsequently the frame will intervene in the banner by exactly 1px on every border. 

2. Data size
The advertising system has a maximum data size set for every banner, therefore if the creation exceeds this limit even by a single kilobyte, it will not be accepted.

Solution
Adhere to the maximum allowed data sizes. If the creation cannot be compressed to a smaller size, negotiate permission for higher data size for a supplementary charge with the dealer. 

3. Aggressive animation
The animation is too fast or various elements of animation alternate in quick sequence.

Solution
Keep a fluent course of the animation and beware of markedly changing colors, headings and other significant graphic elements, which may disturb the user when working with the page. 

4. Wrong functionality of interactive formats
All interactive formats must have precisely defined functionality according to the specification.

Solution
Create both creations exactly according to the specification.
