In V3 you can add mini's to the base. These 40 or 50 ml bottles are pretty small if you compare it to the 700 ml bottles. If you put a 800px height image of a mini in your collection, it doesn't look very realistic. On the other hand, we also want to see the bottle.
A mini is around 11cm tall. A full bottle is around 30cm tall. We can now calculate the height of the image.
30 cm = 800 px
11 cm = 293 px (so somewhere between 290 and 300px)
When adding a image of a mini to the base, we are gonna use two different images. One image with the mini scaled (for the collection page) and one image of the mini on 800px height. You can find an example here:
The steps for making or editing this:
Make the image 800px height and 400px width, the top of the (mini)bottle must hit the top of the image and the bottom of the bottle must hit the bottom like this:
This image is not for the collection page, but for checking the type of bottle and label etc.. After uploading this image to the base you can scale the image to 300 px height by 150 px width. After that, set the Canvas Size to 800 x 400px again and give the bottle a possition on the bottom of the image.
After this, the image looks like this:
On this way the mini's have a realistic height in your collection.
Most of the 200 ml bottles are 21 cm, thats 560 px of height.
The bottles of Malts of Scotland and the old Signatory Dumpy's are 22 cm = 590 px height
Hope it helps!
