minecraft main menu json file download free online no virus no clickbait

Hello there, I installed Custom Main Menu mod, as well as Resource Loader (1.12.2 with other mods (82 in total) + optifine), followed your steps, and, an image I want to be displayed, appears in black & pink/purple (It's some kind of band on the left with the different buttons displayed above it). Can you help me to figure out what's wrong?

here's the result (black+pink squares) (+the bottom text is centered in full screen, so it doesn't really matter if it is a bit decentered in windowed mode):

here is the location of the file (it is called 'transparent.png'):

and here's the config, it's located in 'bandeau' section, everythings works except that:

            {     "images":     {         "bandeau":         {             "image" : "textures:gui/transparent.png",             "posX" : -310,             "posY" : 0,             "width" : 224,             "height" : 373,             "alignment" : "top_center"         }, 	 	"title":         {             "image" : "custommainmenu:textures/gui/minecraft.png",             "posX" : -298,             "posY" : 20,             "width" : 375,             "height" : 375,             "alignment" : "top_center"         },                  "edition":         {             "image" : "custommainmenu:textures/gui/edition.png",             "posX" : -235,             "posY" : 47,             "width" : 96,             "height" : 12,             "alignment" : "top_center"         } 	     },          "buttons":     {         "singleplayer":         {             "text" : "menu.singleplayer",             "posX" : -298,             "posY" : 28,             "width" : 200,             "height" : 20,             "action" :              {                 "type" : "openGui",                 "gui" : "singleplayer"             }         },                  "multiplayer":         {             "text" : "menu.multiplayer",             "posX" : -298,             "posY" : 52,             "width" : 200,             "height" : 20,             "action" :              {                 "type" : "openGui",                 "gui" : "multiplayer"             }         },                  "mods":         {             "text" : "fml.menu.mods",             "posX" : -298,             "posY" : 76,             "width" : 74,             "height" : 20,             "action" :              {                 "type" : "openGui",                 "gui" : "mods"             }         },                      "options":         {             "text" : "menu.options",             "posX" : -220,             "posY" : 76,             "width" : 74,             "height" : 20,             "action" :              {                 "type" : "openGui",                 "gui" : "options"             }         },                  "quit":         {             "text" : "menu.quit",             "posX" : -298,             "posY" : 100,             "width" : 200,             "height" : 20,             "action" :              {                 "type" : "quit"             }         },                  "language":         {             "text" : "",             "posX" : -142,             "posY" : 76,             "width" : 20,             "height" : 20,             "action" :              {                 "type" : "openGui",                 "gui" : "languages"             }         },                  "refresh":         {             "text" : "",             "posX" : -118,             "posY" : 76,             "width" : 20,             "height" : 20,             "texture" : "custommainmenu:textures/gui/buttons.png",             "action" :              {                 "type" : "refresh"             }         }     },          "labels":     {         "modpack name":         {             "text" : "Custom Minecraft 1.12.2 ModPack",             "hoverText" : "§nCustom Minecraft 1.12.2 ModPack",             "posX" : -618,             "posY" : -20,             "color" : -1,             "alignment" : "bottom_right",             "action" :              {                 "type" : "openGui",                 "gui" : "credits"             }         },                  "fml":         {             "text" : "",             "posX" : 23,             "posY" : -70,             "color" : -1,             "alignment" : "bottom_left"         }     },          "other":     {         "splash-text":         {             "posX" : -98,             "posY" : 55,             "color" : -256,             "alignment" : "top_center",             "texts" : "file:minecraft:texts/splashes.txt"         },          "panorama":         {             "images" : "minecraft:textures/gui/title/background/panorama_%c.png",             "animate" : true,             "animationSpeed" : 1,             "blur" : true,             "gradient" : true         }     } }

Thanks in advance (and sorry if there is some few language mistakes, I'm a 16 y/o French boy!)

Edit: Okay nevermind, I've fixed it, we need to set the image files in the mod, by opening it with winrar, now it works!
