As soon as we have there has been a misunderstanding, then I explain.
Again.

The site consists mainly of so-called entities. For example, species of other taxa, photos, copies of literary sources, those in the Community. And users manipulate these same entities.
Each entity has properties.For example, photographs - is the number on the website, the image file, the author, date taken, and other comments. Pay attention: the image file - it is one of the only properties of nature (although very important, even fundamental).Theoretically, an entity may change any of the properties, but that it remained the same essence as that was, it must have at least one unique attribute, which never changes. This property is for still images, and other entities - Id, a unique number.If you downloaded separately two identical images - they are two different entities with two different numbers, even though the original image file and all the signatures to it may be the same.
If the theory is clear, now to practice:
You have downloaded in the photo gallery №1 ezkemplyara butterfly №1.A year later, we made the picture better and for the same instance / angle etc. uploaded a better image - fotorafiya instance №2 №1. In this case. You can not. Remove. Photographs. Room. One. Instead, you need to have photos №1 (an entity, not just a picture, remember, is not it?) To replace the property "image file" in the new picture.Alternative explanation: if you do not have the fifth tooth, you do not need a new fifth tooth next to the seventh or first, you need a new fifth tooth flat on the fifth place of the old.

If something remains unclear - ask, I will explain once again.

And then all beat around the bush? Peter put their conditions vykladyvanii kollektsionnyhPodcherkivayu collection and not on the nature! shots are certain requirements (it is not a requirement request) -and all by itself will come full circle litter site svoya.Necha different there, "fotami with mobile phones" without rezkozti.Then tighten the time the replacement of the add for the best.Pervosti I have the same errors were, but now I think once is better to sweat during filming, and then in Photoshop, then to not be ashamed of the wasted years!
