如何使用「图片复制拼接（重复平铺）」？How do I use the Duplicate Image (Repeat in a Grid) tool?
在「图片复制拼接（重复平铺）」中，选择或拖入文件，按需设置「列数」、「行数」、「间距（像素）」、「间距 / 背景颜色」、「镜像」等选项，然后点击每个结果旁的「下载」按钮即可；有多个文件时也可以点「全部下载（ZIP）」一次打包下载。In the Duplicate Image (Repeat in a Grid): Choose or drop your files, set "Columns", "Rows", "Spacing (px)", "Gap / background colour", "Mirror", then click the Download button next to each result (with several files, "Download all (ZIP)" saves them together).
间距和背景颜色怎么用？How do spacing and the background colour work?
间距是相邻两份图片之间的像素数。勾选“间距和背景透明”时，间隙是透明的（导出 PNG 或 WebP 才能保留透明，JPG 会填成白色）；取消勾选后可以选一种颜色填充间隙，原图透明的地方也会显示这个颜色。Spacing is the number of pixels between neighbouring copies. With Transparent gaps & background ticked the gaps are transparent (keep PNG or WebP output for that; JPG fills them with white). Untick it to fill the gaps with a colour, which also shows through any transparent parts of the original.
镜像翻转有什么用？What is mirroring for?
隔一列（或隔一行）把图片水平（或垂直）翻转，相邻两份的边缘正好对上，可以把一张普通图片拼成没有明显接缝的对称图案，常用于做背景纹理和包装图案。Every other column (or row) is flipped horizontally (or vertically) so the edges of neighbouring copies match, turning an ordinary picture into a symmetrical pattern without obvious seams — useful for background textures and packaging patterns.
最多能复制多少份？How many copies can I make?
行和列各最多 50，但拼好的图片每边不能超过 16384 像素、总共不超过 1 亿像素（浏览器画布的上限）；超过时会提示，请减少份数或先缩小原图。Up to 50 columns and 50 rows, but the finished image must stay within 16,384 px per side and 100 megapixels (the browser's canvas limit). You'll be told if it's too big; use fewer copies or shrink the original first.
