Open a library and use the button in the header: **Add media** for pictures, **Add font**, **Add vector**, **Add mockup**, or **Add color**. Everything you add gets an **Option ID**, which is how your options later say *this choice uses that picture*. ## Upload pictures, fonts or vectors The Upload images dialog with three queued picture tiles, each showing its file name, size and an Option ID badge, above a drop zone reading Drag .gif, .jpg, .png files or a whole folder here with Add more files and Upload a folder of images buttons. Three ways to get files in: * Drag files onto the box. * Click **Add images** and pick them. * Click **Upload a folder of images** and pick a whole folder. Handy for a set of 200 that already lives in one place. ### What each library accepts | Library | Accepted files | | ------- | ------------------------------ | | Image | `.gif` `.jpg` `.png` | | Font | `.woff` `.woff2` `.ttf` `.otf` | | Vector | `.svg` `.pdf` `.eps` `.ai` | Anything else is left out and a message tells you how many were skipped. Files you've already queued are ignored rather than added twice. **WebP pictures are not accepted here.** Convert them to PNG or JPG first. The only route that takes a WebP is the ZIP import further down this page. ### The queue | Rule | Detail | | ---------------- | -------------------------------------------------------------------------------- | | Per upload | Up to **1,000 files** in one go | | Saved in batches | **200 at a time**, one batch fully finished before the next starts | | Thumbnails | Shown up to 200 files. Past that you get names and icons, to keep the page quick | | Order | Drag a tile to move it. The order you leave them in is the order they're saved | | Remove | The **x** on a tile drops it from the queue | **Save** starts the upload. Each tile fills with a progress bar, and if one fails the button becomes **Retry** and only the failed files go again. Tiles already uploaded are outlined in green, so a retry never re-sends work that succeeded. ### Option IDs Every tile carries a badge like **Option ID 7**. That number is the item's handle inside the library, given in the order the files are saved. It matters because a picture choice in an option set stores the Option ID, not the file name. That's why the picker in [Connect options to your design](/optionsets/connect-to-a-template) shows *id: 1*, *id: 2* beside each picture. Name your files in the order you want them offered before you upload, or drag the tiles into that order. Renaming a file afterwards doesn't renumber anything. ### After the upload Customei makes smaller copies of every picture so your storefront loads quickly. The dialog stays open and shows each item going from **optimizing** to **ready**, then you click **Done**. You don't have to wait. Close it and the work carries on, and the list shows which items are still being processed. ## Add colours A colour library has **Add color** instead of an upload box. The Add color dialog showing a Name field reading Black with the help text Auto-generated from color. Edit to customize, a colour picker, HEX and RGBA fields, an eyedropper, and a row of preset swatches. Pick from the presets, drag on the picker, type a **HEX** code, or use the eyedropper to grab a colour off your screen. The name fills in from whatever you land on, so type over it if you'd rather call it *Brand navy*. ## Bring in a whole ZIP **Import** takes a `.zip` and unpacks it into a library. Use it when someone sends you a folder of 300 designs. The Import Assets from ZIP dialog with a Select ZIP file drop zone reading Drop a .zip file here, max 10MB, and a Destination section offering Import to current library or Create new library. | | | | ----------------- | --------------------------------------------------------------------------------------------------------------------------------------- | | **File** | One `.zip`, up to **10MB** | | **What it takes** | Pictures `.png` `.jpg` `.jpeg` `.webp` `.gif` `.svg` `.bmp` `.tiff`, fonts `.ttf` `.otf` `.woff` `.woff2`, and `.psd` files for mockups | | **Destination** | The library you're in, or a brand new one you name here | Drop the file in and Customei reads it without importing anything yet: you get a list of what it found, a count of supported files, and a count of anything it will skip. A ZIP cannot mix loose files at the top with folders. Put everything in folders, or everything at the top level. Mixed, the import refuses to start and tells you so. **Start Import** runs it in the background. You can leave the page: a banner keeps you posted and tells you when it's done. ## Where to next Everything you've uploaded, and what uses each file. Why topping up a library updates your options for you. Turn a library into choices your customer can pick. Back to making the box.
